UPPER MOLE This district is bounded on the north by the ridge of the chalk hills, on the south by the Sussex border, on the east by a line running north from near Copthorne past Home and Bletchingley to the chalk near White Hill, and on the west by the Upper Wey and Arun districts. Except at the western end there is now a very considerable widening of the Wealden formation, and a corresponding narrowing of the Lower Greensand. Hence the sandy heaths give place to meadow and arable lands, the common heath plants are no longer a striking feature, and the pine woods in great measure disappear in favour of green copses, consisting mainly of deciduous trees and shrubs. Among the plants may be mentioned a rare form of bitter cress (Cardamine Hayneana) which occurs near Red Hill and near Horley ; the common lady's mantle (Alchemilla vulgaris) ; a milk vetch (Astragalus glycyphyllos) which with the everlasting pea (Lathyrus sylvestris) is abundant on the hills east of Merstham ; a starwort (Callitriche vernalis) not certainly known to occur elsewhere in the county ; the ivy- leaved campanula (Wahlenbergia hederacea) formerly found on Reigate Heath, and recently re- discovered in the neighbourhood (C. E. and E. S. Salmon). The wild tulip (Tulipa sylvestris) is, I believe, really wild in a meadow by the river Mole near Buckland, where it seldom flowers ; the wood barley (Hordeum sylvaticum), rare in the county, is abundant in several copses in the chalk above Dorking. On this formation the ragged robin (Lychnis Floscuculi), a plant usually found in wet lowland spots, occurs on the top of Box Hill, and also on a high bare chalk hill in Gatton Park. The following is a list of the more interesting species : Ranunculus tripartitus DC. var. intermedius, Hiern.
